How to use this in a composite action?

[PaulRBerg]

I’m looking to create a composite action, and the task that I’m working on would be easiest to implement by doing some work in JavaScript and some other work in a Bash script. Can I use this action (github-script) to achieve this?

I added this to my action:

uses: "actions/github-script@v6"
with:
  script: |
    const script = require("./dist/index.js")
    script({core})

But then I got this error when I ran it:

Error: Cannot find module '/home/runner/work/v2-core/v2-core/dist/index.js'

  code: 'MODULE_NOT_FOUND',
  requireStack: [
    '/home/runner/work/_actions/actions/github-script/v6/dist/index.js'
  ]
}

What am I doing wrong?

Side note - why not enable discussions in this repository?

The path is relative to the current working directory, which isn't the same as the directory where the composite action was checked out.

I don't know the right path at the top of my head, but it might be inside runner.temp - https://docs.github.com/en/actions/learn-github-actions/contexts#runner-context

👍 Good idea, I've enabled discussions.

@PaulRBerg github.action_path might be what you're looking for:

The path where an action is located. This property is only supported in composite actions. You can use this path to access files located in the same repository as the action. https://docs.github.com/actions/learn-github-actions/contexts

So maybe something like this will work:

uses: "actions/github-script@v6"
with:
  script: |
    const script = require("${{github.action_path}}/dist/index.js")
    script({core})

Oh, yes. This was exactly what I needed. Thanks for digging this up, Josh!

Perfect answer, just what I was looking for, thanks @joshmgross!
